| Abstract: | We propose a simple parametrization of the nucleon gluon and sea quark structure functions at allx, and allQ 2. We use the DTU parton model to fix the parametrization at a reference point (Q 0 2 =1.25 GeV2 andA 2=0.01 GeV2) and we mimic the QCD evolution by replacing the dimensioned parameters of the DTU parton model by functions depending onQ 2. |
